What is a Fishbone Diagram used for in safety analysis?

• A. A cause-and-effect chart identifying contributing factors like human, mechanical, environmental, or procedural causes.
• B. A tool to analyze pilot reactions to stimuli.
• C. A checklist for preflight inspection.
• D. A chart showing pilot fatigue levels.

Answer: (A)

A Fishbone Diagram helps you map out the potential root causes of a safety issue by organizing contributing factors into major categories such as human, equipment, environment, and procedures. You place the problem at the head of the diagram and draw a backbone, with wide branches for broad categories and smaller offshoots for specific causes. This visual layout encourages a team to brainstorm comprehensively and connect symptoms to underlying factors, guiding root-cause analysis and targeted corrective actions. It’s not used to analyze pilot reactions to stimuli, nor as a preflight checklist, nor to chart fatigue levels—those tasks rely on different methods or instruments. In safety analysis, this diagram helps reveal where problems originate across people, equipment, procedures, and environment so investigations address the true causes rather than just surface symptoms.
